The invention relates to portable hoppers. One of the objecte of the invention is to provide a portable hopper having a body comprising a hopper from which the supporting truck may be readily withdrawn.

A further object of the invention is to provide a portable hopper having means for supporting the hopper when the truck is withdrawn therefrom and means for readily raising and lowering one end of the hopper for discharging the contents thereof from the opposite end.

For a more comprehensive and clearer understanding of the invention reference may I1OW behad to the following specification taken together with the accompanying drawings in which the preferred embodiment of the invention is shown and in Which:

Figure 1 is a plan view of the underside of the device.

Figure 2 is a longitudinal vertical section taken on line 22 of Figure 1.

Figure 3 is a side elevation of the portable hopper with the supporting truck detached showing the means for supporting one end of the hopper and mechanism for raising and lowering the other end, the hopper being indicated in the raised position by dotted lines. Figure 4 is a side elevation of the hopper showing the pivoted support for the discharge end thereof when the supporting truck is withdrawn from thereunder.

Figure 5 is a transverse vertical sectional view taken on line 55 of Figure 4.

Figure 6 is a front end view of the hopper shown in raised position after the removal of the supporting truck from thereunder.

Like reference characters indicate like parts throughout the several figures thereof. The portable hopper comprises a body 10 whieh is preferably constructed of sheet metal suitably secured to an angle iron frame work 11. The body 10 being open at the top having side Walls 12 and 13 which taper or converge from the front end 14 to the rear end 16. The bottom of the hopper from its approxifl1ate center inclines upwardly to the rear end as indicated at 18. Wheels 19 50 are suitably mounted on the truck frame 21.

1929. Srial No. 373,327.

The frame 21 is substantia;llyrectangular in shape, the side mefnbers there0f 'eXt end-J ing beyond the reartransverse member s as at 22. U-shaped brackets 23 secured to 'th bottom 17 'of the body portion 10 receive the extensions 22 of the truckframe 21.in Slding engagement therein( V Secured to the forward trahsverse 'member of truck frame 21 is drawbar 24 which ex-* tends outwardl from the frame and beyond' the front Wall 14 ofthe b'ody portion 10 in order that it rnay be secured to a motor ve hicle for toWing the portable hopPer. An angle iron 27 is Secured to the front wall'. 14 of the body portion by itsvertical flange and has an aperture through the horizontal flange therof for the reception therein"off r a bolt 28 passedtherethrugb and into an 'opening in the draw bar WhiCh registerS with the aperture in the angle 'iron for Seuring. the body portion 10 to'the-draw bar 24 therby preventing the withdrfifival of'extensions 22 of the truck frame 2 1 fromthe U-shaped member 23. In the rear'end Wall 16fof the body portion 10is a gate extnding transversely across the entire end of the body portion 10 and slidablyengages tratcks' 27 secured to the opposite sides 12 and 13 of the body portion 10. A lever 28 pivotedat the approximate center of transverse braee 28(z as at 40 is also pivotally sCured to the gate as at 41, for raising and lowering the gate" in order. to discharge'the Contentsflof the body in such proportions as"may be desired. Support 29 havirig divergent legs 42'and 43 and transverse braces 44 and 45, is pivotally related to sleeper 46 at the'rear end lof the body portion 10 for-hlcrumingthe bodyportion thereon in order to discharge the contentsof the bod by raising the forward end thereof. It will be noted (see Fig. 4) that the-base of support29 is elevatdabove the roadway--- A tilting mechanism con1prising spaced the course of travel of the portable apart standards 31 having sheaves 32 ro-- tatably m0unted at their upper ends for the passage thereover of cables '33, is providedk or raising and -lowering the receiving end' of the'hopper which is pivOted at its disand pivoted lever means for raising and 10W- charge end on support 29 for the purpose of ering the gate.

discharging the contents of the hopper by gravity through gate 26 when the front end of the hopper is -raised above the top of support 29. Standards 31 of the aforesaid tilting mechanism are provided with braces 49 pwotally: related t;0 the standards at their upper ends and adjacent the upper ends of the standards and are for the purposes of' preventing the tilting of the standards.when

power is applied to cabls 33 by the tow motor, for instance, for raising the receiving endof the hopper. Cables 33 may be afiixed to the receiving end of the hopper in any suitablemanner asuat 34. If desired,a winch:

of the usualeonstrnction may beprovided forv the raiSing and lowering Of the receivinend offlthe hopper.

.]3t will be nted; (see Fig, 2) that the .axle of.t-he tru:ck is positioned forwardly of the center of' the body portion 10 whioh Will result in ,the gravitation dOwnw-ardly of the discharge end of the body portion until it conies.to test uponrthe: support 29,at hih; ti 'me power may be. applied to cables 3.3. the re.deivihgendof the body snpported thereby,andthe pin '26 b withdrawn from en gagement with: the angle iron. and the draw 30;;bar. and the towing motor moved .away from and! outxof engagement With the hopper at which time thereceiing end:of the -hopper.
